T0 on whom, it may concern:

Be it known that I, FREDERICK HART, a

subject of the King of Great Britain, residing at Poughkeepsie, in thecounty of Dutchess and State of New York, have invented a new and usefulImprovement in Perforating-Machines, of which the following is aspecification.

This invention relates to machines for per forating sheets of paper orother thin material with rows or lines of erforations extending atpredetermined distances across each sheetas, for instance, in sheetswhich are used for check-books containing on each sheet several checksseparated by rows of perforations.

The invention relates to improvements in a perforating-machine whichconsists in its general features of a perforating mechanism providedwith punches, needles, or other devices which operate upon the sheets,endless tapes, strings, or aprons arranged in front of the perforatingmechanism for conveying the sheets to the same, a drop-gage or frontstop arranged in front of the perforating mechanism for stopping eachincoming sheet and re leasing itat the proper time to be conveyed by thefeed tapes, strings, or aprons to the perforating mechanism when thelatter is ready for the reception of the sheet, rear drop gages or stopsarranged in rear of the perforating mechanism for stopping the sheet inthe proper position toreceive the perforations, and carrying tapes,strings, or

aprons arranged in rear of the perforating mechanism for moving thesheets from one rear gage to another in order to receive successivelines of perforations and for finally discharging the sheets from theperforating mechanism.

Theobjects of the invention are to rovide improved operating mechanismsfor t e perforating device and gages whereby the actions of thesedevices relative to each other are more accurately timed and will not beaffected by the adjustments of the gages to produce the desiredarrangements of the to' be differently arranged, and to improve themachine in other respects with a view to increasing its efficiency,accuracy, and general usefulness.

Like letters of reference refer to like parts in the several figures.

The main frame A of the machine may be of any suitable construction,that shown consisting of connected side frames and a transverseconnecting yoke or portion a. The perforating mechanism also may be ofany suitable construction as the desired style of work or otherconsiderations may require. The perforating mechanism shown in thedrawings is constructed as follows: B representsa,vertically-reciprocating cross-head arranged transversely in themachine and provided at its lower side with punches, needles, or othertools I) for operating upon the sheets. B represents the bed platearranged beneath the cross-head and provided, if necessary, with adie-plate. The crosshead is carried by upright side posts I), whichslide in suitable guides on the sides of the main frame, and isreciprocated from a horizontal shaft 0, which is journaled in the lowerportion of the yoke a and is provided near its ends with cranks oreccentrics c, Fig. 3, working in boxes 0 at the lower ends of the sideposts I) of the cross-head to raise and lower the latter. Thiscrank-shaft is normally stationary, but is coupled to and uncoupled froma continuously-rotating hollow shaft D by a clutch and actuatingmechanisms which are controlled by the operating mechanism for thereargages, as hereinafter described, so that the crank-shaft makes onerevolution and reciprocates the cross-head once each time the'sheet isarrested by the operation of one of the gages. This hollow drive-shaft Drotates about the crankshaf.t C and is driven from a main drive-shaft E,journaled in the rear portion of the machine, as by a belt e,-connecting belt-pulleys e e on the hollow and main drive-shafts.

F represents the upper, and F the lower, endless front feed aprons,tapes, or strings, which are arranged with their horizontal carryingportions adjacent to each other in front of the bed-plate B, so as totravel with their carrying portions from the front end of the machinetoward the perforating mechanism and carry the sheets F between them tothe same. These endless feed-carriers run around upper and lower frontrollers ff and upper and lower rear rollers f f, respectively. Any usualor suitable means may be employed for tightening the feed-tapes, so thatthey will properly feed the sheets. As shown, the upper front roller isjournaled at its ends in arms f having split upper ends clamped about atransverse frame-rod f which construction permits the arms to be securedat such angle as may be necessary to tighten or slacken the upperfeed-tapes and cause them to properly bear on the sheets resting on thelower tapes. The lower front tapes are kept taut automatically andretained at the proper distances apart by a grooved roller f journaledin a rocking frame f Figs. 1 and 2, provided with a weight f whichpresses the tightener-roller up against the under runs of the lowertapes. These carriers may be driven by any suitable mechanismforinstance, as shown in Figs. 1, 7, and 8, by gearwheels g g g g g 9connecting the hollow shaft D with the lower front roller f, andgear-wheels g 9, connecting the lower and upper front carrier-rollers.Preferably the two gear-wheels g g are loosely mounted on an axle orshaft 9 Fig. 8, and their hubs are provided with cooperatingclutch-teeth g". The wheel g can be slid on its axle to engage anddisengage the clutch teeth without throwing the gear-wheel out of meshwith its driving gear wheel g. A hand-lever 9 Figs. 1 and 8, extendingto the front of the machine, is connected to the sliding gearwheel 9 andby operating this lever the gear wheel 9 can be uncoupled from thegearwheel 9 and the sheet-carriers thus stopped whenever this isnecessary or desirable for any reason.

H H represent the rear carrying aprons, tapes, or strings arranged inrear of the perforating mechanism and running around upper and lowerfront rollers h h and upper and lower rear rollers k 71/ These carriersmay be driven by any suitable mechanismfor instance, as shown in Figs. 1and 2, by a'shaft 7?, arranged longitudinally at one side of the machineand connected by bevel-gearing 71, at its front end with the gear-wheelg and by bevel-gearing h at its rear end and gearwheels 7L7 7L8 with thelower rear roller 71, of the rear carriers. The upper and lower rearrollers k 7&3 are connected so that the upper roller is positivelydriven, as by gear-wheels h", one of which is shown in Fig. 2. The upperrear carrier-tapes are preferably tensioned similarly to the upper frontcarriertapes by adjusting the upper rear roller 7L2, and a swingingtightener-roller h is provided, which bears down on the lower runs ofthe lower rear tapes and automatically maintains the desired tension ofthe latter.

To prevent the rear carriers from pulling on the sheets and tearing themwhile being perforated, the front roller h of the upper carrier is somounted that when the cross-head descends to perforate the sheet theroller h is lifted from the sheet. Any desired or suitable mechanism maybe employed for this purpose. As shown in the drawings, the roller isjournaled in levers h, Figs. 3, 26, and

27, which are guided vertically by the frame and are fulcrumed at h onthe frame with their free ends extending in the path of thereciprocating cross-head. When the latter descends to perforate thesheet, it strikes the free ends of the levers h and lifts the roller itoff of the sheet, so that when the needles or tools engage the sheetthere is no rearward pull thereon and the tools will make sharp cleanperforations. As the tools recede from the sheet the roller 71, againdescends by gravity into operative engagement with the sheet.

1, Figs. 1, 2, and 26, represents the front gage or stop arranged asuitable distance in front of the perforating mechanism and adapted toarrest the forward movement of each sheet before the same reaches theperforating mechanism and to release the sheet at the proper time forfeeding it by the front carriers to the perforating mechanism. The

front gage is operated by an intermittently- .moving mechanism which ispreferably constructed as follows: As shown in the drawings, the frontgage is mounted upon a rockshaft 1' and drops by gravity into the pathof the sheets to arrest them. The rock-shaft is j ournaled on the frameabove the path of the sheets and is provided at one end with a lever i,one end of which is adapted to strike an adjustable stop-screw i Figs.4, 8, and 25, ot limit the drop of the gage. The other end of the leveri is engaged by the rear arm of an operating-lever i pivoted between itsends one side of the frame. By depressing the at front arm of theoperating-lever i the lever i and the rock-shaft are oscillated to liftthe gage.

K, Figs. 2, 4, 5, 21, and 23, represents an intermittently-movingcarrier for the tripdogs, arranged at the same side of the machine asthe front-gage-operating lever, and preferably consisting of an endlesssprocketchain passing around sprocket-wheels k k at the front and rearends of the machine. The rear sprocket-wheel k rotates loosely on asuitable stud-shaft k Figs. 4 and 6, which is adjustably secured to theframe for properly tensioning the dog carrier. The front sprocket-wheel7c (see Fig. 13) is journaled to rotate on the shaft of the lower frontroller of the front carrier and is provided with planetary bevelgear-wheels k, which are arranged between and mesh with a bevelgear-wheel 1c, secured to said tape-roller, and an oppositelydisposedbevel gear-wheel M, which is also loose on the shaft of said feed-rollerand has secured thereto or is formed with a gearwheel is. Thisgear-wheel 7r is driven in a direction opposite to that of thefeed-roller each time the crank-shaft C is rotated to operate theperforating mechanism by suitable means, such as gear-wheels k k k 7c7r, connecting it with said crankshaft C. The opposite rotation of thebevel-gears k k on the opposite sides of the planetary gears it causesthe sprocket-wheel 1c, to which the planetary gears are secured, toremain stationary whenever the crank-shaft and perforating mechanism arein operation, whereas when the gear-wheel k and bevel-gear k are heldstationary by the non-rotation of the crank-shaft O the sprocket-wheel7c is caused to rotate in the same direction as the feedroller. Thus thedog-carrier is moved forwardly when the sheet is moving and theperforating mechanism is inactive and is held at rest while the sheet isstationary and during the action of the perforating mechanism. Thedrive-gearing for the trip-dog carrier is so proportioned that thecarrier travels at the same speed at the feed-carriers and sheets.

The dog-carrier is provided with a series of pivoted trip-dogs Z, whichnormally lie in a horizontal or inactive position, but are turned into avertical or active position, so that they will strike and depress therear arm of the gageoperating lever i in passing over it. The trip-dogsare arranged closely together on the carrier, and as the latter movesalong certain of the dogs are automatically turned up into activeposition at the proper distances apart. The distance between the activedogs will be greater or less according to the length of the sheets beingoperated upon and should be equal to the length of the sheet plus thedistance required between successive sheets. The dogs are turned intoand out of active position by the means shown in Figs. 4, 21 to 23 Mrepresents a dog-setting lever which is pivoted on an adjustablefulcrum-block m and has an arm m extending up to a point just beneaththe upper run of the dog-carrier and an arm m depending below the lowerrun of the dog-carrier. The setting-lever is returned to the positionshown after being oscillated by a spring m connecting its upper arm to afixed arm m on thefulcrumblock. The lower arm of the lever is pro videdwith an upwardly-extending finger m adapted to engage a dog and turn itup into vertical position each time the setting-lever is oscillated. Thefinger m is preferably pivoted on the setting-lever and is heldyieldingly in the upright position shown by a spring m, which connectsthe finger and settinglever and presses a stop-lug m on the fingeragainst the lower arm of the setting-lever. This construction enablesthe finger to yield in case it should be raised in advance of and shouldbe struck by one of the dogs. When a trip-dog which has been turned upinto ver tical position passes around the sprocketwheel 7c, it willdepend from the upper run of the carrier in position to strike and movethe upper arm m of the setting-lever as it passes the same, so that eachdog oscillates the setting-lever and causes it'to raise a succeedingdog. The distances between the successive active trip-dogs will be thesame so long as the position of the setting-lever is not changed. Byadjusting the setting-lever toward or from the sprocket-wheel 1c dogs atshorter or longer intervals will be set in active position, thusadapting the machine for operati on upon sheets of different lengths.The setting-lever may be adjustably secured in any suitable manner. Asshown, the fulcrum-block m rests on a slotted guide m and has aclampbolt m provided with a head located in an undercut portion of theguide-slot and with an operating cam-lever m To the latter is alsoconnected a slide-pin m Figs. 23 and 23 adapted to enter either of aseries of holes m in the top of the guide m By rais ing the cam-leverthe fulcrum-block is unclamped and the pin m raised out of the hole inwhich it is engaged. The fulcrumblock, with the setting-lever, can thenbe moved to the desired position and secured by turning down thecam-lever. The slide-pin and holes gage the positions of the setting-lever, and the clamp prevents any movement of the fulcrum-block whensecured. The upper and lower runs of the dog-carrier are guided in upperand lower ways n n, which are arranged on the frame between thesprocket-wheels 7c 7c for the carrier and are connected at their ends bysemicircular cover-plates n inclosing the outer portions of thesprocket-Wheels. The ways are wide enough for the passage of the dogs inthe horizontal position, and the upper way has bottom plates n formingbetween them a slot through which the dogs depend when in the verticalor active position and which holds the dogs in the active position.

at, Figs. 4, 21, and 23, is a guide-cord arranged adjacent to the lowerrun of the dogcarrier and secured at its rear end to a portion of theframe and at its front. end to a semicircular guide-flange n on thecoverplate n forthe front sprocket-wheel. Between its ends the cordpasses through and is adapted to slip in an oblique hole in the arm mtofthe fulcrum-block for the dog-setting lever. In rear of this arm 7% theguide-cord is held far enough from the dog-carrier to allow the dogs toretain their horizontal position, while in front of the arm the cord isheld nearer to the dog-carrier, so that the tripdogs, which are set inupright active position, are held in such position by the guide-cord andcurved guide-flange n until they reach the cover around the frontsprocket-wheel and enter the slot of the upper way for the dog carrier.After the trip-dogs pass around the rear sprocket-wheel they strike aninclined face n, Fig. 6, on a flange-plate of the lower way and arethereby thrown down to the normal horizontal position. To hold thedog-carrier positively from backward movement or play, aclutch-ball nFigs. 5 and 6, is preferably interposed between a grooved I circulardisk n on the rear sprocket wheel 75 and an inclined face on a flange non the rear cover-plate, which encircles the flange of thesprocket-wheel.

n Figs. 1, 21, and 23, is a bent springplate secured to thesupporting-block of the dog-setting lever and beneath the free end ofwhich the trip-dogs pass. This spring-plate will turn down any dog whichmay be slightly raised.

Each active dog actuates the front-gageoperating lever and lifts thegage as it passes the lever, and as the active dogs are spaced as statedand travel at the same speed as the sheets the operations of the gageare timed to insure the proper feeding of the sheets to the perforatingmechanism.

0 O O 0 Figs. 1, 2, 4, 13, and 14, repre sent the rear gages or stops,which are arranged in rear of the perforating mechanism for arrestingeach sheet successively in the proper positions to receive successivetransverse lines of perforations at the desired distances apart. Theserear gages are held normally in an elevated position, and each gage islowered at the proper time to arrest the sheet and hold it in positionwhile the mechanism perforates the sheet. A greater or less number ofthese gages may be used in accordance with the number of lines ofperforations which are to be formed in the sheet. WVhen the front gagehas been lifted to feed a sheet to the perforating mechanism, the frontrear gage is dropped, so that the sheet which is being fed to theperforating mechanism is arrested by this rear gage and held in positionwhile the crosshead descends and the line of perforations is formed anduntil the sheet is released from the perforating mechanism by thefollowing upward movement of the crosshead. The first rear gage is thenraised and releases the sheet, which is now fed onward by the rearcarriers against the second rear gage, which has been lowered in time toarrest the sheet in the proper position to receive the second line ofperforations. This operation is repeated with reference to every one. ofthe rear gages until all the desired lines of perforations have beenformed in the sheet. The raising of the last rear gage releases thesheet, which is then removed by the rear carriers. Each rear gage isadjustable toward and from the perforating mechanism, so that the gagescan be set to form the perforations at the desired distance from thefront end of the sheet and at the desired distances apart. The mechanismshown for supporting and adjusting these gages is constructed .asfollows: Each gage consists of a hollow sleeve p, journaled to rock onan inclosed supporting-shaft p and having projecting fingers or lugs 29for engaging and arresting the sheets. The supporting-shaft (see Figs.18 and 14) is journaled near its ends in adjustable bearing-blocks p andis pro- TDD vided outside of the bearing-blocks with gear-pinions p,which mesh with stationary toothed racks p on the sides of the frame.The shaft has milled heads 1) at its extremities for turning it andcausing the pinions to roll along the toothed racks. The twobearing-blocks p are connected by a cross-bar p arranged below thegage-sleeve, and are guided by ribs engaging in horizontal ways or slots19 in the sides of the frame. are secured in position by clamp-bolts p.passing through the blocks and provided with heads engaging in undercutportions of the guideways p and nuts at their upper ends for drawing theheads of the bolts up against the flanges of the ways. ing-blocks aresplit, and the clamp-bolts also serve to contract the portions of theblocks about the gage-shaft p to hold the latter from turning. When theclamp-bolts are loosened, the gage-shaft can be turned in its bearingsand the intermeshing pinions, and racks will cause a correspondingmovement of both ends of the shaft, thus always main taining theparallelism of the gage in its different ad'ustments. After adjustmentthe bearing-blocks are secured and the gageshaft clamped against turningby tightening up the clamp-bolts It sometimes happens that the printingon the sheets is not exactly parallel with the edge o the sheet, and inthat casein order to make the rows of perforations parallel with theprinted mat ter the gages must be set at a slight obliquity to hold thesheets at a corresponding angle to the line of feed. For this purposeone of the 'gear-pinions p for instance, that at the lefthand end of theshaft in Figs. 13 and 14is loose on the gage-shaft and is releasablyconnected thereto, as by a slide-bolt 13 working in a hole in a fixedcollar 1) on the shaft and adapted to engage in a hole in the pinion.The bolt has a pin 13 entering an inclined slot 1) in a rotatable ring10 surrounding the collar p By turning the ring 1) the bolt can bewithdrawn from its hole in the pinion p and the latter uncoupled fromthe shaft. When the pinion is free, the gage-shaft can be moved slightlyfrom its true transverse position for the purpose explained.

The gages can be conveniently placed in the proper position by markingthe lines of perforations on a sheet of paper and slipping the sheet aainst a stop-pin 19 Figs. 4 and 4 on the side of the frame and behind aclamping-spring 29 which holds the sheet in position while the gages arebeing set.

The rear gages are operated in succession by theintermittently-traveling trip-dogs Z, which operate the front gage,preferably through the following means: Each reargage sleeve is providedat one end with a fixed arm 9, Figs. 14, 17, and 18, connected by asuitable spring g with a stationary arm or projection g on the adjacentbearing- They The bear-.

block for the gage. This spring holds the gage-sleeve in the normalposition with its fingers elevated and returns the sleeve and fingersafter operation by the traveling tripdogs. g is a rock-arm, preferablyloose on the gage-shaft adjacent to one end of the gagesleeve andconnected to the latter by a springrod a, Fig. 14, which causes thesleeve to rock with the arm, but permits it to yield somewhat relativeto the arm. The rockarm g has a projection g Fig. 20, adapted to engagea stop pin or part q on the adjacent bearing-block for the gage-shaft tolimit the return movement of the gage-sleeve by its spring. The rock-armQ3 extends up toward the upper run of the dog-carrier in the path of thedepending active trip-dogs, so that each active dog in passing engagesand rocks the arm from the position shown in Fig. 17

to that shown in Fig. 18, thereby rocking the gage-sleeve to. loweritsfingers into position to arrest the sheet. The dog carrier is stoppedwhen the dog reaches the position shown in Fig. 19 and remainsstationary, holding the gage down, while'the perforating mechanism isoperated to perforate the sheet and then starts again, so that thetrip-dog passes and releases the rock-arm, permitting the return of thearm and gage under the action of the spring g.

The mechanism shown for starting and stopping the trip-dog carrier isconstructed as follows, (see Figs. 12 to 14, 17 to 19, and 28 1) Rrepresents a gear-segment mounted loosely on each gage-shaft beside therock-arm g and having teeth meshing with teeth on an upright plunger orrack 7", which slides in a guide in the adjacent bearing-block for thegage-shaft and the movements of which are limited by a in r thereonentering a slot in the bearinglilock. The gear-segment has an arm whichextends toward the path of the active tripdogs Zon the upper run of thedog-carrier and is engaged and rocked by each active tripdog with therock-arm g beside which it is located. The arm of the gear-segment R issomewhat shorter than the rock-arm g and the trip-dog has a beveled facer opposite the end of the gear-segment arm, so that the latter isreleased by the trip-dog after lowering the. plunger and is permitted toreturn while the rock-arm g is still engaged by the dog. The plungers rfor the several gages rest at their lower ends on a horizontal bar S,arranged longitudinally of the machine and connected to a rockshaft s,journaled on the adjacent side of the frame. The rock-shaft s isconnected to a clutch mechanism for connecting the operating crankshaftC for the perforating mechanism with its hollow driveshaft D, and eachtime the bar S is depressed by either of the plungers r the clutch isoper ated to couple the shafts for one revolution. As shown in Figs. 9and 12, the rock-shaft s has 2. depending arm connected to one end ofand the sliding clutch member.

a rod 8, which extends horizontally inward and is connected by asuitable spring .9 with the frame-yoke a. This spring acts to return thebar, plunger 1*, and gear-segment when released by the trip-dog.

Any suitable clutch mechanism may be employed, which when tripped willconnect the crank-shaft C of the perforating mechanism to the hollowdrive-shaft D and automatically release it after one completerevolution. The clutch mechanism shown in the drawings is constructed asfollows, (see Figs. 7 to 11 z) T represents a clutch member formed on orsecured to the hollow drive-shaft D and having teeth interlocking withteeth in a cooperating clutch member T, which is splined or otherwiseslidably mounted on the crank-shaft C, so as to turn therewith. Thesliding clutch member T is pressed toward the other member by a springat, surrounding the crank-shaft between the bearing therefor Urepresents a clutch-shifting lever pivoted at its lower end on theframe-yoke and extending up beside the hub of the sliding clutch member,and U an upright safety-lever also piv .oted at its lower end to theframe-yoke. The upper ends of these levers are connected by a strongspring u, which tends to pull the levers toward each other againstsuitable stops u a on the yoke. 11. is a lug projecting from the hub ofthe sliding clutch member and having a double-beveled or V-shaped frontedge, and a is a detent pivoted on the shifting-lever and normallypressed against the lug u by a spring a between the detent and theshifting-lever. A gravity-latch a, pivoted on the shifting-lever,normally rests with its free end in a seat at the upper end of thedetent and holds the latter against movement away from the lug n on theclutch member. it represents a latch-tripping finger which swings fromone arm of a bell-crank lever u pivoted on the frame-yoke, and has ahook at its lower end adapted to engage under a shoulder on the latch.(See Figs. 9 to 11.) The other arm of the bell-crank lever 11. isconnected to the rod 8, which connects with the clutch-controlling barS. In the normal or rest position the sliding clutch member is held outof engagement with its cooperating member against the action of itsspring t by the stronger spring a, connecting the shifting and safetylevers, and the parts occupy the position shown in Fig. 9 the detentbeing held by the latch against the lug on the clutch member andpressing the lug over the top of a stationary projection 11. on theframe-yoke and against the inclined face of a lug u on the safety-lever.WVhen the bell-crank lever u is rocked by the depression of theclutchcontrolling bar S, the trip-finger is lowered, and when the bar Sand bell-crank lever are returned by the spring .9 the trip-fingerengages and lifts the latch u. The detent now being freed cannot holdthe sliding clutch member, and the latter is moved by its spring t intoengagement with the cooperating clutch member, and the sliding clutchmember and crank-shaft to which it is connected revolve, thus carryingthe lug u away from the detent a. The detent is then pressed out by itsspring 11. and the latch again drops into engagement with the detent.When the lug 11. comes around into engagement with the beveled face a ofthe detent, it and the clutch member are moved over until arrested bythe engagement of the lug with the stationary projection to on the yoke,thereby partially but not wholly disengaging the clutch-teeth, as shownin Fig. 9. As the space between the end of the detent and the stationaryprojection u" is less than the thickness of the lug m the shifting-leverU is moved away from its stop, and the spring u, connecting the shiftingand safety levers, is strained. As soon as the lug of passes thestationary projection u on the yoke the spring it pulls theshifting-lever suddenly toward its stop and throws the sliding clutchmember out of engagement with the other clutch member, the parts thenbeing again in the rest position. (Shown in Fig. 9 The engagement of thelug a with the lug on the safety-lever stops the rotation of the clutchmember and crank-shaft andprevents any over movement thereof. Thus thecrank-shaft C makes one revolution and raises and lowers the cross-headof the perforating mechanism each time one of the rear gages is loweredto arrest the sheet. As the dogcarrier can only move, as above eX-plained, when the crank-shaft is stationary, the rear gages are notreleased by the tripdogs and raised until after the lifting of thecross-head.

In this machine the carriers travel continually and the sheets arearrested and held by the rear gages against the action of the travelingcarriers. When released by the gages, the sheets are immediately movedagain by the carriers, since the sheets are at all times under theinfluence of the traveling carriers. The traveling trip-dogs move alongwith the sheet and operate the several rear gages in succession at theproper times to arrest the sheet in the different positions necessaryfor making the successive lines of perforations.

Either of the rear gag-es can be rendered inactive when it is notrequired, as when a sheet is to have a less number of lines ofperforations than there are rear gages. This is accomplished in themachine shown by the following means: A slotted spaceblock V, Figs. 14and 16, straddles each rear gageshaft between one end of the gage-sleeveand the adjacent bearing-block for the shaft and holds the sleeve insuch position as to keep the rock-arm R and gear-segment in position tobe actuated by the traveling trip-dogs.

The space-*block is retained on the gage-shaft by a spring-clip 12,which embraces the shaft and is held from movement by the engagement ofa pin 1) on the adjacent bearingblock in one of two holes 11 in thespaceblock. By removing the space-block the gage-sleeve can be shiftedendwise on the gage-shaft and the rock-arm g and gear-segment R alsomoved on the gage-shaft out of the path of the traveling trip-dogs, sothat the latter can pass the rock-arm and gear segment without actuatingthem and the gage and clutch mechanism whicn they control. To hold theparts in the shifted position, the space-block can be engaged on thegage-shaft between the opposite bearingblock .and the gear-segment. Thespaceblock is held in this new position, as in its original position, bythe engagement of a pin 12 on the bearing-block in the other of the twoholes 0 in the space-block. When the gage-sleeve is so shifted to itsinoperative po sition, it is held against turning under the action ofits spring by a stop-pin 12 Fig. 14,

which projects inwardly from the bearlngblock 29 toward which thegage-sleeve has been shifted and under which pin the adjacentgage-finger p engages.

While the machine is especially designed for operating upon the sheetsof paper and other light material by perforating the same, it is obviousthat it might be applied to other purposes by providing the cross-headwith the proper tools for effecting the desired operation.
